Abstract:
Based on the 677 stations daily observation data（1954—2003）of frost in China as long and new as possible, which were processed by the National Meteorology In formation Center, the distribution of the frost days in China is analyzed, the s patialtemporal trend of regional frost days and the interdecadal variation f eatures are obtained, and the response of frost to global warming is further dis cus sed. The results indicate an obvious reduction trend of frost days in the whole China, especially in 1990s. We can also find that the earlier last frost day and the later first frost day are related with the rising daily minimum temperature and ground temperature, which will possibly cause the reduction of frost season .
